Welcome to your interview.
The question is on your right: Handling Missing Data and Bias. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
What statistical techniques would you use to handle missing data or selection bias in an empirical economics study?
